Serverless Stack

Hi, how do I do this in functional stack?:
```    this.addOutputs({
      ApiEndpoint: this.api.customDomainUrl || this.api.url,
    });```

oh yes I tried this and for some reason my intelisen got stuck and couldn't find this. Thanks!

is this is also alternative to this?:
```  const layer = LayerVersion.fromLayerVersionArn(this "Layer", layerArn);
  const layer = LayerVersion.fromLayerVersionArn(<http://ctx.app|ctx.app>, "Layer", layerArn);```

anywhere you see `this` you can put `ctx.stack` there
